Thiourea is non-autofammable.
The test determines the ignition temperature of a
deposited dusty test substance on hot surfaces. The test is conducted
according to the test protocol. The surface area of the substance is
increased intentionally in this test by preparing the test substance
accordingly to simulate the deposited dusty properties. The ignition
temperature of deposited dusty test material is expected to be lower
than the ignition temperature of the solid with larger particle
Melting of the test substance was observed from 240
°C on with slight hissing noise, foaming and smoke development
(increases with increasing temperature). Thus, thiourea was categorized
in BWZ 1.
